HINIIDIFIER.

1924. serial No. $6,332.

This invention relates to an improved humidifier. More especially itrelates to improved means constituting both a support for a humidifierand a conduit for water that passes through the motor thereof. Theinvention in its broader aspects is disclosed and claimed in our(zo-pending application, which has become Patent No. 1,504,431 of August12, 1924, entitled Humidifiers, of which this is a division.

In humidiiiers embodying a water motor for driving a fan, thehuimidifier as-a whole, including the casing, water motor, fan and spraynozzle, are usually suspended from some overhead support by hangers orthe like. In addition the water used as motive force has been conductedto the motor through supply pipes, and away from it through dischargepipes. The present invention provides for the elimination of some ofthese parts, in that it combines them into tubular members which serveboth as conduits for the Water and as supports for the apparatus; andthis particular division thereof provides conduit hangers havingconnections with a water motor which dis charges its used water throughthem into the base or pan without separate drainage piping beingrequired.

It is a feature of the invention that this discharge is conductedthrough the conduit hangers into the pan of the humidifier casing, andthence flows olf through the ordinary drain pipe.

Accordingly the hangers are made with tubular sections to which thecasing is attached, or which may in fact be part of the casing, andintol which suitable connections lead froin the discharge exits of thewater motor. At the lower ends of the tubular sections, just beforetheir junction With the pan, openings are provided in the sections fromwhich the water may dis charge into the pan. The flow of this waterhelps flush the pan and carry off foreign matter through the regulardrainage system thereof.

In the accompanying drawing, the invention is shown in its particularapplication to 'a motor having a two-way discharge, but this is merelyillustrative of the principle of the invention. The patent is intendedto cover, by suitable expression in the appended claims, whateverfeatures of patentable novelty exist in the invention disclosed, and notheretofore claimed in our co-pending application hereinbefore mentioned.

In the drawings:

Figure 1 is a front elevation, showing a humidifier embodying thepresent improvements;

Figure 2 is a side elevation of the same, looking from the right ofFigure 1; and

Figure 3 is an enlarged elevation showing the details of the lower endof one of the conduit hangers.

Referring to the drawings, a nozzle 10, Within the humidifier casing 11provides a conical spray above which a water motor 12 is supportedcarrying on its shaft a fan 13 which forces air through the casing andthrough the conical spray. The casing as a whole is supported by a pairof hanger members each having a tubular portion 14 whose upper endscrews into a socket 15 attached to the ceiling, and whose lower endengages a perforated nut 1G having a stem 18 which projects downwardthrough the bottom of the pan 19 to receive a clamping nut 20 forholding the pan. The outlets from the motor are connected direct to thetubular portions 14 through two-part tubular connections 21 each havinga union 31 in its midst, between its two parts` Water may be supplied tothe motor through a branch 22 of the main supply system 23 for thenozzle, there being a control valve 24 and filter 25 in the system aheadof the branch and a diaphragm control valve 26 between it and thenozzle, by which the performance of the humidifier can be automaticallycontrolled by any well known means of humidity regulating appara-tusrThe water having done its work in driving the motor passes through theconnections 21 into the tubular portions 14 of the conduit hangers, andthence through them to the nuts 16 where it fiows out through the holes27 to the pan. It then drains from the latter into the waste pipe 28,assisting by its volume and force in removing any lint or foreignparticles that may be deposited on the pan.

The tubular hangers thus serve both as sel-iai No. 4,633. Divided andaus` application inea Narni i,
